Hi,

How can I set input a NULL value into an IBOQuery? I'm trying to do the
following:

IBOQuery1.ParamByName('DATE1').AsDate := SomeDate;
IBOQuery1.ParamByName('DATE2').AsDate := NULL;

NULL can't be casted as a date, but when using IB_Query I can use
AsVarient.

How can you do this with IBOQuery?

Thanks!
